Fade In/Out and V-mute menus inactive

FAQ ID：KB01300001 | Date： 2013/07/23

Fade In/Out and V-mute menus are inactive. How do I solve this problem?

To apply Fade In, Out or V-mute, the target track must be chosen in advance. If they are inactive, confirm that a target track is selected. If not, please click the track panel (the panel will be gray) and then apply the effect.
